A person swims at 135^(@) to current to river, to meet target on reaching opposite point.The ratio of person's velocity to river water velocity is

A person swims at 135^(@) to current of river, to meet target on reaching opposite point. The ratio of person's velocity to river water velocity is

A person swims at 135° to current of river, to meet target on reaching opposite point. The ratio of person's velocity to river water velocity is

A person swims at 135° to current of river, to meet target on reaching opposite point. The ratio of person's velocity to river water velocity is

A swimmer wands to cross a river and reach point B directly from A . The speed of the wimmer in still river and that of river flow are same. The dotted line AN is normal to flow direction of river. For swimmer to reach point B , the angle his velocity relative to river will make with line AN is given by theta . then the value of theta is :

A swimmer starts to swim from point a to cross a river. He wants to reach point B on the opposite side of the river. The line AB makes an angle 60^(@) with the river flow as hown. The velocity of the swimmer in still water is same as that of the water (i) In what direction should he try to direct his velocity ? Calculate angle between his velocity anf river velocity. (ii) Find the ratio of the time taken to cross the river in this situation to the minimum time in which he can cross this river.
